Answer:

x=-12

Step-by-step explanation:

x^2-24x+144=0

When you see it as =0, that doesn't mean it's 0. it means it needs more deep solving.

x^2+24x+144-144=0-144

x^2+24x=-144

x^2+24x+12^2=-144+12^2

x^2+24x+12^2=0

(x+12)^2=0

x+12=0

x=-12

Answer:

x = 12

Step-by-step explanation:

Step 1: Write quadratic

x² - 24x + 144 = 0

Step 2: Factor

(x - 12)(x - 12) = 0

Step 3: Find roots

x - 12 = 0

x = 12

What value of x makes this equation true 12x-15=6-3x

Alex

Answer:

x = 1.4 (or 21/15)

Step-by-step explanation:

12x - 15 = 6 - 3x

+3x +3x

-----------------------

15x - 15 = 6

+15 +15

-----------------------

15x = 21

/15 /15

----------------------

x = 21/15 or

x = 1.4

Seth is using the figure shown below to prove Pythagorean Theorem using triangle similarity. In the given triangle ABC, angle A

lana66690 [7]

The relationship between the lengths of the sides of a right triangle are

given by Pythagoras theorem.

Part A: <u>ΔABC is similar to ΔADC</u>

Part B: ΔABC and ΔADC are similar according <u>AA similarity postulate</u>

Part C: <u>DA = 6</u>

Reasons:

Part A:

∠A = 90°

Segment AD ⊥ Segment BC

Location of point D = Side BC

Part A: In triangle ΔABC, we have;

∠A = 90°, ∠B = 90° - ∠C

In triangle ΔADC, we have;

∠ADC = 90°, ∠DAC = 90° - ∠C

∴ <u>ΔABC is similar to ΔADC</u> by Angle-Angle, AA, Similarity Postulate

Part B: The triangles are similar according to <u>AA similarity postulate</u>,

because two angles in one triangle are equal to two angles in the other

triangle and therefore, by subtraction property of equality, the third angle

in both triangles are also equal.

Part C: The length of DB = 9

The length of DC = 4

Required: Length of segment DA

In triangle ΔABD, we have;

∠BDA = 90°= ∠ADC

∠DAC ≅ ∠B by Congruent Parts of Congruent Triangles are Congruent

Therefore;

ΔABD ~ ΔADC by AA similarity, which gives;

$\displaystyle \frac{\overline{DA}}{\overline{DC}} = \frac{\overline{BD}}{\overline{DA}}$

$\overline{DA}^2$ = $\overline{DC} \times \overline{BD}$

Which gives;

$\overline{DA}^2$ = 4 × 9 = 36

$\overline{DA}$ = √(36) = 6

$\overline{DA}$ <u> = 6</u>

DiKsa [7]

Answer:

Amount of milk in each milkshake = 7 2/3 gallons

Step-by-step explanation:

Gallons of milk = 23 (given)

Number of Milkshakes = 3

Because the gallons of milk were shared equally,

Amount of milk in each milkshake = 23/3 = 7 2/3 gallons of milk

Use the commutative property to simplify the expression 4/3 + 3/4 + 2/3

saw5 [17]

The simplified expression using the commutative property is : $\frac{6}{3}$ + $\frac{3}{4}$

<h3>Meaning of commutative property</h3>

commutative property can be defined as a mathematics attribute that is possessed by a mathematical equation, that enables the objects undergoing addition or multiplication to change position.

In conclusion, The simplified expression using the commutative property is : $\frac{6}{3}$ + $\frac{3}{4}$

<h3>Analysis</h3>

4/3 + 3/4 + 2/3 = ( $\frac{4}{3}$ + $\frac{2}{3}$ ) + $\frac{3}{4}$ = $\frac{6}{3}$ + $\frac{3}{4}$
